Y=-2x+7 That is the equation written in y=mx+b formula
Answer:
Subtract the discount price from the full price. Divide the amount of change by the original price.
Step-by-step explanation:
Example: Original price = $40 Sale price = $30
$40-$30= 10
10/40= 1/4
1/4 = .25 or 25%
Answer:
y=2x+1, assuming my change in the reported data was correct.
Step-by-step explanation:
The data for x had one more entry than the values for y. I removed the second "0" so that the x and y points line up, as shown in the attached image. The data indicate a straight line, with a slope of 2 (y increases by 2 for every x increase of 1). The y-intercept is 1, as per the first data point (0,1).
Answer:
The width is independent, w, and the length is dependent, 2w - 5. If discussing the area then the independent is w and the dependent is Area for A = (2w-5)(w).
Step-by-step explanation:
On a graph called the coordinate plane, there are two axis. The horizontal axis is the x-axis and is known as the independent variable. A great example of an independent variable is time. Time is always represented on the x-axis because time passes by. It does not depend on anything.
The other axis is the y-axis. It is the vertical axis on the graph. It is called the dependent variable because its value depends on x. For example, if you were looking at miles per hour, the number of miles would depend on how many hours you traveled. You have to know the time to find miles. This is a dependent variable.
Here w can be anything and it affects what the length 2w - 5 will be. It determines it because it is part of the expression. The independent variable is w and the dependent variable is the length 2w - 5. If discussing the area then the independent is w and the dependent is Area for A = (2w-5)(w).
Answer:
$57.50
Step-by-step explanation:
- 75(0.2 discount)
- =15
- 75-15
- =50
- 50(0.15 sales tax)
- =7.50
- 50+7.50
- =57.50
Can you mark me brainliest on both of my answers pleaseee. I would appreciate it (✿◠‿◠)
